Teng Mu

Chinese scholar of the Sung Dynasty who adopted a position similar to that
of Lucretius and other proponents of atomism
with respect to extraterrestrial worlds. He wrote:

Empty space is like a kingdom, and earth and
sky are no more than a single individual person in that kingdom. Upon
one tree are many fruits, and in one kingdom there are many people. How
unreasonable it would be to suppose that, besides the earth and the sky
which we can see, there are no other skies and no other earths.
